Summary
We used201Tl-chloride for studying and differentiating thyroid areas shown to be ‘cold’ in previous131I or99mTc scanning. We investigated sixteen thyroid neoplasms that were removed surgically shortly afterwards. We found an intense intranodular accumulation of201Tl in five scintigraphs shown to be of histologically malignant neoplasms, and an intense accumulation also in one of those shown to be histologically benign. We did not detect any201Tl-chloride accumulation in two cases of thyroiditis; one of these had shown an intense accumulation in a previous131Cs scintigram.
